Surya Digital - Building Native iOS Components in React Native - Part 1 (Old Architecture)

This guide walks through how to build native iOS components for React Native using the older architecture. It explains when and why you might need to write native code, like when you need access to iOS-specific features, better performance, or existing native libraries. It also breaks down the differences between the old bridge-based approach and the newer JSI-based setup. Along the way, you’ll learn how to create native modules and UI components step by step, with clear examples in Objective-C and Swift. Important basics like common React Native macros and ways for JavaScript and native code to talk to each other—using callbacks, promises, and events—are covered in a straightforward way.

Surya Digital - Building a Scalable Theme System in React

Building scalable theming in React involves treating themes as centralized configuration objects rather than scattered CSS hacks. This post guides you through designing flexible, maintainable, and portable theme systems using React Context, inline styles, and sound architecture. It covers common pitfalls, project scaling, and UI library integration.

Surya Digital - Transaction Isolation Level In PostgreSQL

Most developers assume they know what `READ COMMITTED`, `REPEATABLE READ`, and `SERIALIZABLE` really mean, but PostgreSQL’s MVCC engine has a few surprises in store. This blog unpacks the real behavior behind each isolation level, exposes the anomalies they allow (and why), and shows how PostgreSQL bends the classic SQL-92 model in clever, performance-conscious ways. If you care about data consistency, concurrent transactions, or why `SERIALIZABLE` isn’t just a buzzword, this is the deep dive you didn’t know you needed.

Surya Digital - Building a Hybrid Document Search Engine with Typesense and LLMs

Building an effective document search system requires more than basic PDF parsing. This comprehensive guide demonstrates how to create a hybrid RAG-powered search engine using [Typesense](https://typesense.org)’s dual indexing capabilities, custom PDF processing for mixed content types, and AI-driven visual context preservation. Learn how to handle complex documents with handwritten annotations, extract structured data from tables, and deliver accurate results by combining traditional text search with modern vector embeddings and LLM integration.
